Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features.

[0035] See Figure 1As shown, an embodiment of this application provides a separating device 100 for separating and loosening tobacco blocks. This device enables automated loosening of tobacco blocks while maintaining a constant separating force, reducing tobacco breakage. It should be noted that the separating device 100 provided in this application is not limited to the tobacco processing line in cigarette production; it can also be applied to other material conveying scenarios. For ease of understanding, this application embodiment only uses tobacco production as an example application scenario.

[0036] Specifically, the material separating device 100 includes a separating component 110, a drive component 120, and a control component. The separating component 110 can controllably separate materials to loosen clumps. The drive component 120 has multiple degrees of freedom and a working end; the separating component 110 is mounted on the working end to move along these multiple degrees of freedom under the drive of the drive component 120. The control component is electrically connected to both the separating component 110 and the drive component 120 to control their operation.

[0037] For example, the control component can be set with corresponding set force values ​​according to the different physical characteristics of tobacco shreds. In this way, the control component can reasonably adjust the insertion force of the separating component 110 according to the different physical characteristics of tobacco leaves, ensuring the loosening requirement while reducing the problem of tobacco leaf breakage. Simultaneously, the control component can also acquire the insertion force of the separating component 110 on the material, compare the set force value with the insertion force, calculate a control signal based on the deviation, and control the separating component 110 to adjust the output force to maintain a constant insertion force, ensuring the loosening quality of the tobacco shreds.

[0038] Continue reading Figure 2 As shown, in some embodiments, the insertion assembly 110 includes a cylinder 111 and a plurality of cutters 112, each cutter 112 being mounted on the output end of the cylinder 111. The cylinder 111 is electrically connected to a control assembly to apply an output force to the cutter 112 under the control of the control assembly.

[0039] Specifically, cylinder 111 is connected to an external air compressor system so that, driven by compressed air, its output end can retract to perform up-and-down cutting and separating operations on the cutter 112. The control component is electrically connected to cylinder 111 to control the output force of cylinder 111 to meet the requirements of the corresponding tobacco leaf cutting and loosening operations.

[0040] In some embodiments, the interpolation assembly 110 further includes a connector 113, which is connected to the working end of the drive assembly 120 to maintain the stability of the interpolation assembly 110 and adjust the corresponding working trajectory under the control of the drive assembly 120. The control assembly includes a torque sensor 131, which is mounted on the connector 113 and electrically connected to the control assembly to enable the control assembly to obtain the magnitude of the interpolation force of the interpolation assembly 110.

[0041] Specifically, the control component also needs to include a central processing unit (CPU) with a corresponding control program set within it to adjust the insertion force according to the different physical properties of the tobacco leaves. Simultaneously, the control component acquires the insertion force of the insertion component 110 via a torque sensor 131, forming a constant force control system to ensure torque stability during the insertion process. By using a torque control algorithm and changing the cutting tool 112, different insertion modes are achieved, completing the insertion and loosening of the tobacco leaves, reducing the amount of tobacco leaf agglomeration, improving the loosening effect, enhancing flow stability, and meeting the process requirements for flexible insertion of different tobacco leaves and thin sheets.

[0042] Furthermore, the connector 113 is also provided with a control interface 1131, so that the air pump can be connected to an external air compressor system through the control interface 1131 to realize the extension and retraction drive of the air pump.

[0043] Furthermore, the insertion and splitting assembly 110 also includes a bracket 114, which is mounted on the output end of the cylinder 111, and each tool 112 is spaced apart on the side of the bracket 114 facing away from the cylinder 111.

[0044] Specifically, the bracket 114 can be a metal component, which is set at the output end of the cylinder 111 so that it can move telescopically under the drive of the cylinder 111 and provide a mounting carrier for each tool 112 to ensure the telescopic insertion and splitting operation of each tool 112.

[0045] Furthermore, each cutter 112 is detachably connected to the support 114. This allows for free adjustment of the spacing between the cutters 112 or replacement with different sizes of cutters 112 models, depending on the characteristics of the material, to meet different interpolation modes.

[0046] For example, the interpolation assembly 110 also includes multiple fasteners 115, and the bracket 114 is provided with multiple mounting portions at intervals. Each fastener 115 installs a corresponding cutter 112 onto its corresponding mounting portion. The fasteners 115 can be locking screws, and each mounting portion of the bracket 114 and the cutter 112 are provided with screw holes to lock the cutter 112 onto the bracket 114 by means of the fasteners 115. Depending on the interpolation material, the spacing of the cutters 112 can be adjusted or the model of the cutter 112 can be changed by removing and installing the fasteners 115, thus achieving diverse interpolation requirements.

[0047] In another embodiment, a slide rail can be provided at the bottom of the bracket 114, and each cutter 112 can be slidably connected to the slide rail, so that the spacing of the cutter 112 can be adjusted by sliding the cutter 112.

[0048] In some embodiments, the drive assembly 120 includes a six-axis robot 121, the working end of which is connected to the interpolation assembly 110.

[0049] Specifically, the six-axis robot 121 has six degrees of freedom, including six joint movements: rotation, lower arm, upper arm, wrist rotation, wrist swing, and wrist lateral movement. The six joints combine to achieve six degrees of freedom motion at the end effector, offering advantages such as high flexibility, large load capacity, and high positioning accuracy. Thus, by installing the interpolation assembly 110 at the working end of the six-axis robot 121, under the control of the control unit, the six-axis robot 121 can freely adjust the position of the interpolation assembly 110 and adjust the interpolation motion trajectory.

[0050] When performing the splitting motion, the six-axis robot 121 can maintain synchronous movement with the tobacco blocks on the conveying device 200, ensuring that the tobacco blocks do not accumulate due to the splitting action. At the same time, the six-axis robot 121 can achieve flexible posture swing, which helps to reduce the thickness of the splitting cutter 112, reduce the force during the splitting process, and the adjustable posture swing is beneficial to improving the dispersion effect.

[0051] Furthermore, the drive assembly 120 also includes a base 122 on which a six-axis robot 121 is mounted. The base 122 is mounted on one side of the conveyor 200 to facilitate the installation of the six-axis robot 121 and to ensure that the six-axis robot 121 can drive the insertion assembly 110 to operate above the conveyor 200.

[0052] An embodiment of this application also provides a tobacco shred dispersing device 1000, including the inserting device 100 and the conveying device 200 in any of the above embodiments. The conveying device 200 is used to convey materials, and the inserting component 110 is located above the gravity direction of the conveying device 200.

[0053] Specifically, the conveying device 200 includes a support 114, a conveyor belt, and a drive motor, both of which are mounted on the support 114. The drive motor is connected to the conveyor belt to drive the conveyor belt for transporting the cigarette blocks. A base 122 is located on one side of the support 114 so that the six-axis robot 121 can adjust the position of the insertion assembly 110 above the conveyor belt to meet different insertion operation requirements.

[0054] This embodiment has the insertion device 100 of any of the above embodiments, and therefore has all the beneficial effects of the insertion device 100 of any of the above embodiments, which will not be described in detail here.

[0055] Embodiments of this application also provide a cigarette production system, including the tobacco splitting device 100 or the tobacco dispersing device 1000 described in any of the above embodiments.

[0056] This embodiment has the insertion and separation device 100 or tobacco shred dispersing device 1000 of any of the above embodiments. Therefore, it has all the beneficial effects of the insertion and separation device 100 of any of the above embodiments, which will not be described in detail here.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
